Sometimes you will encounter the following error message when trying to use the ros-gazebo-gym package:

`np.bool` was a deprecated alias for the builtin `bool`. To avoid this error in existing code, use `bool` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the nu
mpy scalar type, use `np.bool_` here.                                                                                                                                                                      
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:

This error is caused by the installed [pandas](https://pandas.pydata.org/ and numpy libraries on your system to not be compatible (see https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations). This happens when you install numpy with pip while pandas is installed through the system repositories. You can solve this issue by uninstalling the numpy or installing pandas using pip (i.e. pip uninstall numpy or pip install pandas).
